A Long Island couple claims singer Marc Anthony jerked them around to get a higher price for his Brookville mansion.

Paul and Patricia Ferrillo say they tried to buy the 10,000-square-foot, 10-bedroom, eight-bath manse where Anthony once lived with Jennifer Lopez but their $2.3 million bid was “buried deep in the waters off Long Island Sound.”

Paul Ferrillo, a disabled lawyer, and Patricia, who suffers with “aggressive breast cancer,” accused Anthony in a lawsuit of having his daughter put in “fake” bids to drive up the price.

The Ferrillos contend Anthony admitted to them in Facebook messages that his daughter “had made sham bids under different names.” The couple refused to provide the messages to The Post.

The 8.5-acre property, which includes two guesthouses and a pool, sold in July for an undisclosed sum. It was initially on the market for $12 million in 2012, according to a report.

Anthony said through a lawyer he was “certainly sympathetic” to the Ferrillo’s “personal circumstances,” but that he denied the “absolutely baseless claims.”
